Allowed Types

At present, only a subset of Go types are supported.

All exported symbols in the package must have types that are supported. Supported types include:

  • Signed integer and floating point types.
  • String and boolean types.
  • Byte slice types. Note that byte slices are passed by reference, and support mutation.
  • Any function type all of whose parameters and results have supported types. Functions must return either no results, one result, or two results where the type of the second is the built-in 'error' type.
  • Any interface type, all of whose exported methods have supported function types.
  • Any struct type, all of whose exported methods have supported function types and all of whose exported fields have supported types.

Unexported symbols have no effect on the cross-language interface, and as such are not restricted.

The set of supported types will eventually be expanded to cover more Go types, but this is a work in progress.

Exceptions and panics are not yet supported. If either pass a language boundary, the program will exit.

  • messageType - The message type of the message. This will be a valid channels.MessageType.
  • message - The contents of the message. The message should be at most 510 bytes. This need not be of data type string, as the message could be a specified format that the channel may recognize.
  • validUntilMS - The lease of the message. This will be how long the message is available from the network, in milliseconds. As per the channels.Manager documentation, this has different meanings depending on the use case. These use cases may be generic enough that they will not be enumerated here. Use channels.ValidForever to last the max message life.
  • tracked - Set tracked to true if the message should be tracked in the sendTracker, which allows messages to be shown locally before they are received on the network. In general, all messages that will be displayed to the user should be tracked while all actions should not be.
  • cmixParamsJSON - A JSON marshalled xxdk.CMIXParams. This may be empty, and GetDefaultCMixParams will be used internally.

Returns:

func (*ChannelsManager) SendGeneric

Call this when returning from sleep and close when going back to sleep.

These threads may become a significant drain on battery when offline, ensure they are stopped if there is no internet access.

Threads Started:

  • Network Follower (/network/follow.go) tracks the network events and hands them off to workers for handling.
  • Historical Round Retrieval (/network/rounds/historical.go) retrieves data about rounds that are too old to be stored by the client.
  • Message Retrieval Worker Group (/network/rounds/retrieve.go) requests all messages in a given round from the gateway of the last nodes.
  • Message Handling Worker Group (/network/message/handle.go) decrypts and partitions messages when signals via the Switchboard.
  • Health Tracker (/network/health), via the network instance, tracks the state of the network.
  • Garbled Messages (/network/message/garbled.go) can be signaled to check all recent messages that could be decoded. It uses a message store on disk for persistence.
  • Critical Messages (/network/message/critical.go) ensures all protocol layer mandatory messages are sent. It uses a message store on disk for persistence.

  "sendToken":true
}

type DummyTraffic

type DummyTraffic struct {
	// contains filtered or unexported fields
}

DummyTraffic is the bindings-layer dummy (or "cover") traffic manager. T The manager can be used to set and get the status of the thread responsible for sending dummy messages.

func NewDummyTrafficManager

func NewDummyTrafficManager(cmixId, maxNumMessages, avgSendDeltaMS,
	randomRangeMS int) (*DummyTraffic, error)

NewDummyTrafficManager creates a DummyTraffic manager and initialises the dummy traffic sending thread. Note that the manager is by default paused, and as such the sending thread must be started by calling DummyTraffic.Start. The time duration between each sending operation and the amount of messages sent each interval are randomly generated values with bounds defined by the given parameters below.

Parameters:

  • cmixId - a Cmix object ID in the tracker.
  • maxNumMessages - the upper bound of the random number of messages sent each sending cycle. Suggested value: 5.
  • avgSendDeltaMS - the average duration, in milliseconds, to wait between sends. Suggested value: 60000.
  • randomRangeMS - the upper bound of the interval between sending cycles, in milliseconds. Sends occur every avgSendDeltaMS +/- a random duration with an upper bound of randomRangeMS. Suggested value: 1000.

func (*DummyTraffic) GetStatus

func (dt *DummyTraffic) GetStatus() bool

GetStatus returns the current state of the DummyTraffic manager's sending thread. Note that the status returned here may lag behind a user's earlier call to pause the sending thread. This is a result of a small delay (see DummyTraffic.Pause for more details)

Returns:

  • bool - Returns true (dummy.Running) if the sending thread is sending messages and false (dummy.Paused) if the sending thread is not sending messages.

func (*DummyTraffic) Pause added in v4.4.4

func (dt *DummyTraffic) Pause() error

Pause will pause the Manager's sending thread, meaning messages will no longer be sent. After calling Pause, the sending thread may only be resumed by calling Resume.

There may be a small delay between this call and the pause taking effect. This is because Pause will not cancel the thread when it is in the process of sending messages, but will instead wait for that thread to complete. The thread will then be prevented from beginning another round of sending.

func (*DummyTraffic) Start added in v4.4.4

func (dt *DummyTraffic) Start() error

Start will start up the Manager's sending thread, meaning messages will

be sent. This should be called after calling NewManager, as by default the
thread is paused. This may also be called after a call to Pause.

This will re-initialize the sending thread with a new randomly generated interval between sending dummy messages. This means that there is zero guarantee that the sending interval prior to pausing will be the same sending interval after a call to Start.

type FileTransfer

type FileTransfer struct {
	// contains filtered or unexported fields
}

FileTransfer object is a bindings-layer struct which wraps a fileTransfer.FileTransfer interface.

func InitFileTransfer

func InitFileTransfer(e2eID int, receiveFileCallback ReceiveFileCallback,
	e2eFileTransferParamsJson, fileTransferParamsJson []byte) (*FileTransfer, error)

InitFileTransfer creates a bindings-level file transfer manager.

Parameters:

Returns:

func (*FileTransfer) CloseSend

func (f *FileTransfer) CloseSend(tidBytes []byte) error

CloseSend deletes a file from the internal storage once a transfer has completed or reached the retry limit. If neither of those condition are met, an error is returned.

This function should be called once a transfer completes or errors out (as reported by the progress callback).

Parameters:

func (*FileTransfer) MaxFileNameLen

func (f *FileTransfer) MaxFileNameLen() int

MaxFileNameLen returns the max number of bytes allowed for a file name.

func (*FileTransfer) MaxFileSize

func (f *FileTransfer) MaxFileSize() int

MaxFileSize returns the max number of bytes allowed for a file.

func (*FileTransfer) MaxFileTypeLen

func (f *FileTransfer) MaxFileTypeLen() int

MaxFileTypeLen returns the max number of bytes allowed for a file type.

func (*FileTransfer) MaxPreviewSize

func (f *FileTransfer) MaxPreviewSize() int

MaxPreviewSize returns the max number of bytes allowed for a file preview.

func (*FileTransfer) Receive

func (f *FileTransfer) Receive(tidBytes []byte) ([]byte, error)

Receive returns the full file on the completion of the transfer. It deletes internal references to the data and unregisters any attached progress callback. Returns an error if the transfer is not complete, the full file cannot be verified, or if the transfer cannot be found.

Receive can only be called once the progress callback returns that the file transfer is complete.

Parameters:

func (*FileTransfer) RegisterReceivedProgressCallback

func (f *FileTransfer) RegisterReceivedProgressCallback(tidBytes []byte,
	callback FileTransferReceiveProgressCallback, period int) error

RegisterReceivedProgressCallback allows for the registration of a callback to track the progress of an individual received file transfer.

The callback will be called immediately when added to report the current progress of the transfer. It will then call every time a file part is received, the transfer completes, or a fatal error occurs. It is called at most once every period regardless of the number of progress updates.

In the event that the client is closed and resumed, this function must be used to re-register any callbacks previously registered.

Once the callback reports that the transfer has completed, the recipient can get the full file by calling Receive.

Parameters:

  • tidBytes - The file transfer's unique fileTransfer.TransferID.
  • callback - A callback that reports the progress of the file transfer. The callback is called once on initialization, on every progress update (or less if restricted by the period), or on fatal error.
  • period - The progress callback will be limited from triggering only once per period. It is a duration in milliseconds. This value should depend on how frequently you want to receive updates, and should be tuned to your implementation.

func (*FileTransfer) RegisterSentProgressCallback

func (f *FileTransfer) RegisterSentProgressCallback(tidBytes []byte,
	callback FileTransferSentProgressCallback, period int) error

RegisterSentProgressCallback allows for the registration of a callback to track the progress of an individual sent file transfer.

The callback will be called immediately when added to report the current progress of the transfer. It will then call every time a file part arrives, the transfer completes, or a fatal error occurs. It is called at most once every period regardless of the number of progress updates.

In the event that the client is closed and resumed, this function must be used to re-register any callbacks previously registered with this function or Send.

Parameters:

  • tidBytes - The file transfer's unique fileTransfer.TransferID.
  • callback - A callback that reports the progress of the file transfer. The callback is called once on initialization, on every progress update (or less if restricted by the period), or on fatal error.
  • period - The progress callback will be limited from triggering only once per period. It is a duration in milliseconds. This value should depend on how frequently you want to receive updates, and should be tuned to your implementation.

func (*FileTransfer) Send

func (f *FileTransfer) Send(payload, recipientID []byte, retry float32,
	callback FileTransferSentProgressCallback, period int) ([]byte, error)

Send initiates the sending of a file to a recipient and returns a transfer ID that uniquely identifies this file transfer. Progress for the file transfer is reported to that passed in callback.

Parameters:

  • payload - JSON of FileSend, which contains the file contents and its metadata.
  • recipientID - marshalled bytes of the recipient's id.ID.
  • retry - The number of sending retries allowed on send failure (e.g. a retry of 2.0 with 6 parts means 12 total possible sends).
  • callback - A callback that reports the progress of the file transfer. The callback is called once on initialization, on every progress update (or less if restricted by the period), or on fatal error.
  • period - The progress callback will be limited from triggering only once per period. It is a duration in milliseconds. This value should depend on how frequently you want to receive updates, and should be tuned to your implementation.

Returns:

Depending on UX requirements, they may still show the state in an altered manner, for example greying out a description. This is designed so when the state is raised, the old configs are maintained. This will unregister / re-register with the push server when leaving or entering the Push maxState. The default maxState is Push will return an error if the maxState isnt a valid state

MaxState can be:

	Mute shows no notifications for the ID.
	- Mute = 0
	WhenOpen shows notifications for this ID only when the app is running and
	open. No registration or privacy leaks occur in this state.
 - WhenOpen = 1
	Push shows notifications for this ID as push notification on applicable
	devices. This state has a minor privacy loss.
	- Push = 2

func NewOrLoadUd

func NewOrLoadUd(e2eID int, follower UdNetworkStatus, username string,
	registrationValidationSignature, cert, contactFile []byte, address string) (
	*UserDiscovery, error)

NewOrLoadUd loads an existing UserDiscovery from storage or creates a new UserDiscovery if there is no storage data. Regardless of storage state, the UserDiscovery object returned will be registered with the User Discovery service. If the user is not already registered, a call to register will occur internally. If the user is already registered, this call will simply load state and return to you a UserDiscovery object. Some parameters are required for registering with the service, but are not required if the user is already registered. These will be noted in the parameters section as "SEMI-REQUIRED".

Certain parameters are required every call to this function. These parameters are listed below as "REQUIRED". For example, parameters need be provided to specify how to connect to the User Discovery service. These parameters specifically may be used to contact either the UD server hosted by the xx network team or a custom third-party operated server. For the former, all the information may be fetched from the NDF using the bindings. These fetch methods are detailed in the parameters section.

Params

  • e2eID - REQUIRED. The tracked e2e object ID. This is returned by E2e.GetID.
  • follower - REQUIRED. Network follower function. This will check if the network follower is running.
  • username - SEMI-REQUIRED. The username the user wants to register with UD. If the user is already registered, this field may be blank. If the user is not already registered, these field must be populated with a username that meets the requirements of the UD service. For example, in the xx network's UD service, the username must not be registered by another user.
  • registrationValidationSignature - SEMI-REQUIRED. A signature provided by the xx network (i.e. the client registrar). If the user is not already registered, this field is required in order to register with the xx network. This may be nil if the user is already registered or connecting to a third-party UD service unassociated with the xx network.
  • cert - REQUIRED. The TLS certificate for the UD server this call will connect with. If this is nil, you may not contact the UD server hosted by the xx network. Third-party services may vary. You may use the UD server run by the xx network team by using E2e.GetUdCertFromNdf.
  • contactFile - REQUIRED. The data within a marshalled contact.Contact. This represents the contact file of the server this call will connect with. If this is nil, you may not contact the UD server hosted by the xx network. Third-party services may vary. You may use the UD server run by the xx network team by using E2e.GetUdContactFromNdf.
  • address - REQUIRED. The IP address of the UD server this call will connect with. You may use the UD server run by the xx network team by using E2e.GetUdAddressFromNdf. If this is nil, you may not contact the UD server hosted by the xx network. Third-party services may vary.

Returns

  • A Manager object which is registered to the specified UD service.

func NewUdManagerFromBackup

func NewUdManagerFromBackup(e2eID int, follower UdNetworkStatus,
	cert, contactFile []byte, address string) (*UserDiscovery, error)

NewUdManagerFromBackup builds a new user discover manager from a backup. It will construct a manager that is already registered. Confirmed facts have already been restored via the call NewCmixFromBackup.

Parameters:

  • e2eID - e2e object ID in the tracker
  • follower - network follower func wrapped in UdNetworkStatus
  • cert - the TLS certificate for the UD server this call will connect with. You may use the UD server run by the xx network team by using E2e.GetUdCertFromNdf.
